WORM (Write Once, Read Many) Cartridges
Certain records retention and data security applications require a Write Once, Read
Many (WORM) method for storing data on tape. The LTO Ultrium 6, Ultrium 5,
and Ultrium 4 drives enables WORM support when a WORM tape cartridge is
loaded into the drive.
WORM Media
Because standard read/write media are incompatible with the WORM feature, a
specially formatted WORM tape cartridge (see Figure 6-2) is required. Each WORM
cartridge has a unique, worldwide cartridge identifier (WWCID), which comprises
the unique CM chip serial number and the unique tape media serial number.
